1 It's enough for payment at least. You just have to hold it close. 2 Apparently, it is. 3 That's true for the default setting, but you can force NFC to be enabled all the time via systemd. I've read multiple reviews on various places and apparently NFC Enabled says "device unsupported" on some devices while it's actually supposed to be supported because it has a good, strong NFC chip. So that's not an accurate app to do the test on the Jolla phone. Gee, thanks for calling me a liar I really did use NFC payment.
